Substitute Part Grouping Explanation

The Molex 0761557604 qualifies as a direct substitute for the 0761556604 based on strict parameter equivalence across all electrical and mechanical specifications. The substitution is valid because both parts share identical characteristics in the following critical parameters:

• Connector type, style, and orientation (Header, Male Pins; Impact, Guide Left)
• Position count and array configuration (192 positions; 12 rows × 16 columns)
• Pitch specification (0.053" / 1.35mm)
• Mounting and termination method (Through Hole; Press-Fit)
• Contact material and finish (Gold; 30.0µin thickness)
• Electrical ratings (30V; 64 Differential Pairs contact layout)
• Environmental compliance (UL94 V-0; ROHS3 Compliant; MSL 1)
• Operating temperature range (-55°C ~ 85°C)

The primary distinction is product status: the 0761557604 is active and available, whereas the 0761556604 is obsolete. The 0761557604 is supplied in Tray packaging, compared to the original part's unspecified packaging format.
